Concussion Testing Pilots Kick Off Fall

August 4, 2015

The Michigan High School Athletic Association kicked off the 2015-16 school year Monday by hosting 70 member high schools for training in two pilot sideline concussion testing programs aimed at assisting in decision-making regarding the removal of athletes from activity after possible concussion events and record-keeping of those events beginning this fall.

Illinois-based King-Devick Test and Maryland-based XLNTbrain Sport each will be used to monitor approximately 10,000 Michigan high school student-athletes drawn from schools representing all four classes and a variety of regions statewide.

The pilot programs are part of a three-pronged advance by the MHSAA in concussion care this fall. In addition to becoming the first state association to offer pilot sideline concussion testing, the MHSAA will be the first to mandate record-keeping by member schools of all possible concussion events from detection to an athlete’s return to play. The requirement applies to both practices and events, all levels of all sports in grades 7 through 12.

The MHSAA also this fall is the first state association to provide all participants at every MHSAA member high school and junior high/middle school with insurance intended to pay accident medical expense benefits – covering deductibles and co-pays left unpaid by other policies – resulting from concussions sustained during MHSAA practices or competitions. There is no cost to either schools or families.

“These pilot programs are intended to not only improve what’s actually happening on the sidelines at practices and contests in these communities that are part of the pilot programs, they’re intended to spread the word of the need for improved concussion detection across every community,” MHSAA Executive Director John E. “Jack” Roberts said. “We hope these schools involved will become involved in their leagues and conferences and with their peers across the state as we expand the awareness of the need for better sideline detection and provide ways to get it done.”

The MHSAA asked schools at the end of this spring to volunteer for the pilot programs and then selected participants in order to guarantee a variety of schools based on enrollment and location. Schools are committed to involving at least two sports for each gender each season.

Schools participating in the XLNTbrain Sport pilot program are: Adrian, Adrian Madison, AuGres-Sims, Bay City Central, Bear Lake, Brethren, Belding, Birmingham Groves, Brighton, Chesaning, Corunna, Detroit Collegiate Prep, East Kentwood, Fennville, Fowlerville, Gibraltar Carlson, Grand Rapids Christian, Grandville, Greenville, Grosse Ile, Hamilton, Harrison Township L’Anse Creuse, Hazel Park, Kalamazoo Christian, Lansing Christian, Macomb L’Anse Creuse North, Owosso, Pewamo-Westphalia, Portland, Reese, Rochester Hills Lutheran Northwest, St. Clair Shores Lakeview, St. Johns, Stanton Central Montcalm, Vermontville Maple Valley, West Bloomfield and Wyoming Kelloggsville.

Schools participating in the King-Devick Test pilot are: Bay City Western, Benton Harbor, Buchanan, Calumet, Caro, Caseville, Detroit Cody, Detroit Martin Luther King, Fenton, Flint Kearsley, Frankenmuth, Fruitport, Garden City, Grand Ledge, Grand Rapids Northview, Lake Leelanau St. Mary, Lake Linden-Hubbell, Lincoln Alcona, Midland Bullock Creek, Montague, Muskegon, Niles, Pontiac Notre Dame Prep, Romeo, Saginaw Heritage, Scottville Mason County Central, Shelby, St. Charles, St. Joseph, Tawas, Vicksburg, Whitehall and Yale.

The King-Devick Test is a rapid eye movement screening evaluation that requires athletes to read single-digit numbers displayed on a tablet computer in order to detect impairments of eye movement, attention, language, concentration and other symptoms of abnormal brain function. The test has been validated in more than 50 recent peer reviewed articles published in elite medical journals and is associated with the Mayo Clinic.

The test is administered on the sidelines during evaluations for suspected head injuries, and the post-injury results are then compared to an athlete’s preseason baseline. Any worsening of performance (increased time and/or errors) suggests a concussion has occurred and the athlete should be “removed from play” for further evaluation.

“The first and most critical step in managing concussion in the youth athlete is to recognize when one has occurred – not always a simple task,” said Dr. David Dodick, professor of neurology and director of sports concussion services at the Mayo Clinic. “The King-Devick test helps take the guesswork and subjectivity out of the sideline evaluation in a rapid, accurate, and objective way.”

XLNTbrain Sport includes balance and web-based neuro-cognitive tests also used before the start of a season to create a baseline measurement of reaction time, attention, inhibition, impulsivity, memory, information processing efficiency and executive function. The test also assesses mood, anxiety, stress and emotionality.

After a possible head injury, a sideline assessment is done using a smartphone or tablet with those results then compared with the athlete’s baseline measurements. The program documents the severity of a concussion, provides a guide for on-the-field decision making regarding treatment and recovery time and can report results via email to parents, coaches, training staff and medical professionals.

Dr. Harry Kerasidis, who designed the XLNTbrain Sport software, presented at the Coalition for Concussion Treatment Summit at the United Nations building in 2014.

“We included an objective balance test that relies on smartphone accelerometer technology which is effective in the field during practice and game situations,” Kerasidis said. “Should a concussion injury be suspected, the system automatically generates a notification to parents and medical professionals and creates a recovery protocol and post-injury tracking so the right people can monitor the athlete’s progress. Then, the system assists medical professionals with the all-important return-to-learn and return-to-play clearance.”

Father & Son Set to Meet for 1st Time Coaching from Opposing Benches

The bantering back and forth is almost complete.

Mid-MichiganOn Thursday, Mike and Zachary Zyla will finally coach against each other in a varsity girls basketball game.

It’s a game that both coaches circled months ago when Zachary, 26, got his first head coaching job at Britton Deerfield.

“It’s going to be intense,” Zachary said. “I’m sure he will want to win just as badly as I will. Me and our girls have been talking about the game a lot because it’s a game we think we can win. We want to beat Sand Creek.”

Mike Zyla coaches Sand Creek and is Zachary’s dad. He is a longtime coach in cross country and track and added varsity basketball to his resume three years ago. Zachary, who played at Sand Creek, was hired this past offseason to coach the Patriots.

Both schools are in the Tri-County Conference.

“It’s going to be fun,” Mike said. “We’ve been going back and forth about it for a couple of weeks. We’ll see how it goes.”

Basketball is special in the Zyla household.

Zachary’s other brother, Ryan, coaches at a junior college in Minnesota. His sister, Chelsi, played two years of college basketball after graduating from Sand Creek. Their mom, Kirsten, keeps the scorebook for Mike’s games. She is a special education teacher at Britton Deerfield.

“When basketball season rolls around, that’s all we talk about,” Zachary said.

“I guess it’s a little bit in the bloodlines,” Mike said.

After graduating from Sand Creek in 2018, Zachary served in the Navy. He returned home two years ago and served two seasons as his dad’s assistant.

“I just love the game of basketball,” he said. “I’ve been playing since I was probably 2 years old. It’s the thing I’m passionate about. I watch almost every night. If it’s not a live basketball game, I watch clips of old games. I’m just a junkie for basketball.”

Mike said he misses having his son on his bench.

“I miss having him on staff,” Mike said. “He’s really sharp, picking stuff up on the fly. It was nice having him on the sidelines with me. It’s a good opportunity for him, though.”

Zachary accepted the job in time to have a summer program with BD.

“I’ve always been a big fan of basketball,” he said. “It’s in my blood. I started coaching the Sand Creek hoopsters when I was 16 years old. I knew that’s what I wanted to do. I would say coaching at the varsity level was a goal of mine. It’s always been a dream of mine. I didn’t expect to get a head coaching job so soon. I’d like to get to the next level someday.”

He said he has a few new things for his team to run against his dad.

“He taught me a lot, but our coaching strategies are different,” Zachary said. “I think I’m going to have some things he hasn’t seen yet.”

Sand Creek and BD both lost their season openers Tuesday. Since BD’s game started at 4:30 p.m., Zachary was able to get to Sand Creek to see his dad’s game against Pittsford.

“He was able to scout us,” Mike said.

It’s all in good fun.

“We have a great relationship,” Zachary said. “We bounce ideas off each other all of the time. Even for our first game of the season, we were talking about what we should do, the offenses and defenses. We talk pretty much every day.”

As rare as it is for a father and son to coach against each other, it’s the second time it’s happened in Lenawee County in recent years. Hudson varsity boys basketball coach Jeff Webster coached against his son, Jamison Webster, when Hudson played Tecumseh two seasons ago.

Jamison said it was a great experience, one the Zylas will never forget.

“Coaching and competing against my dad’s teams at Hudson over the last few years has been a great experience,” he said. “We both want to win, being the competitors we are. That being said, the lifelong memories we have made being able to share a sport we both love is what makes it special.”

Zachary said he knows it will be a little different than normal.

“The game’s intensity will be higher than most nights,” he said.

Mike agreed. He doesn’t relish the idea of beating his son, but doesn’t plan on backing down. Since they are both in the TCC, they’ll face off again later this winter.

“We’re both pretty competitive,” he said. “Competitive genes are in the family. I don’t think either one of us will be very happy if we are on the losing side Thursday night.”
